European leaders pushed forward their demand that Russia implement a total land, air and sea ceasefire in Ukraine by midnight Monday or face crippling sanctions. The Europeans reiterated their ultimatum after Russian President Vladimir Putin rejected the ceasefire and proposed holding direct negotiations with Ukraine in Istanbul on Thursday instead.

France said on Monday that leaders at a meeting on Ukraine this weekend had asked the European Commission to put together new "massive" sanctions targeting Russia's oil and financial sector if Russia failed to agree a ceasefire.
